Alexander Whitestone ec2a427a7a feat: implement A2A protocol for fleet-wizard delegation (#1122) ...

Implements Google Agent2Agent Protocol v1.0 with full fleet integration:

## Phase 1 - Agent Card & Discovery
- Agent Card types with JSON serialization (camelCase, Part discrimination by key)
- Card generation from YAML config (~/.hermes/agent_card.yaml)
- Fleet registry with LocalFileRegistry + GiteaRegistry backends
- Discovery by skill ID or tag

## Phase 2 - Task Delegation
- Async A2A client with JSON-RPC SendMessage/GetTask/ListTasks/CancelTask
- FastAPI server with pluggable task handlers (skill-routed)
- CLI tool (bin/a2a_delegate.py) for fleet delegation
- Broadcast to multiple agents in parallel

## Phase 3 - Security & Reliability
- Bearer token + API key auth (configurable per agent)
- Retry logic (max 3 retries, 30s timeout)
- Audit logging for all inter-agent requests
- Error handling per A2A spec (-32001 to -32009 codes)

## Test Coverage
- 37 tests covering types, card building, registry, server integration
- Auth (required + success), handler routing, error handling

Files:
- nexus/a2a/ (types.py, card.py, client.py, server.py, registry.py)
- bin/a2a_delegate.py (CLI)
- config/ (agent_card.example.yaml, fleet_agents.json)
- docs/A2A_PROTOCOL.md
- tests/test_a2a.py (37 tests, all passing)
